Hotel & Travel Information

This seminar will include a review of statistical theory and present statistical methods, which are used to better select and/or analyze Tolerance Stack-ups. The Probability (RMS) Method, the Monte Carlo Simulation Technique and tolerance optimization techniques will be discussed along with guidelines on which method(s) to use in given situations. Attendees will also view a demonstration of a microcomputer Monte Carlo Simulation program that analyzes the effects of form and assembly variation on the quality of a finished product. This seminar will provide an overview of Design of Experiments (DOE) methods, which enable effective analysis of critical product dimensions and tolerances.

Note: Participants should bring a scientific calculator for several in-class exercises.

Learning Objectives
By attending in this seminar, you will be able to:

  • Apply worst case, root-mean-square, and Monte Carlo simulation methods for the allocation of analysis of simple-to-intermediate complexity tolerancing schemes
  • Use the "Risk of Misassembly" approach for tolerance allocation, and the "Main Effect" approach for determining dimensional variables tolerance which exhibit the greatest impact on build variation
  • Understand and be exposed to various computer tools which can greatly improve their statistical tolerancing efforts, given the intricacies of GD&T, plus-minus tolerancing, and various datum schemes

Who Should Attend
This seminar is intended for engineers and educators who would like to have a good working knowledge of applying statistics to product design in order to better predict and improve product quality.

Prerequisites
An engineering undergraduate degree in any discipline would be beneficial.

  • Probability & Statistics Concepts Required for Statistical Tolerancing Methods
  • Tolerance Allocation Based on "Risk of Misassembly"
  • Statistical Tolerancing Using the Root-Mean-Square (RMS) Method
    • With bilateral tolerances
    • With unilateral and/or asymmetrical tolerances
    • In 2-D and 3-D applications
    • Participant exercises
  • Statistical Tolerancing Using Monte Carlo Simulation
    • Performing Monte Carlo Analysis by hand
    • Demonstrations of computer software for Monte Carlo Simulation and analysis (VSA-2D, VSA-3D and others, if time permits)
  • Analyzing Part Tolerances using Main Effect and Sensitivity Analysis Methods -- Methods for Determining the Contribution of Process Variables to Overall Process Variation. A Brief Description of Partial and Full-Factorial Analysis is Also Provided
  • Overview of Design of Experiments (DOE) and Tolerance Optimization Techniques -- Their Benefits in Effective Tolerancing of Parts and Assemblies
  • Tolerance Management Program Guidelines -- For the Benefit of Participants Interested in Establishing a Comprehensive Quality Assurance Program in Their Organization
